I applied online. The process took 2 days. I interviewed at Capital One (Chicago, IL) in Aug 2021
Interview
Code Signal
There were 4 questions and I clearly remember that two of the questions needed dynamic programming for optimal. Question 1 was very simple and I skipped question 3. I am pretty certain that if you get above a 700 you will be moving on.
Interview questions [1]
Question 1
Minimum peak elements from an array by their repeated removal at every iteration of the array
Surprisingly manageable — the interview felt more like a conversation than an interrogation. It began with a sequence of coding questions, including one on merging overlapping intervals. The real challenge came during system design, where I had to outline a URL shortener service that could scale impressively. Interestingly, I had just looked at a similar architecture on PracHub, which helped me articulate my thoughts clearly. The technical questions wrapped up with validating a binary search tree, and I ended with a positive vibe. I received an offer, but ultimately chose to decline it.
Interview questions [3]
Question 1
Merge overlapping intervals from a list of time ranges
Interviewed for an engineer position, the interview was a joke. Asked basic OOP question with a few follow ups - no system design portion. Interviewer was very laid back and chill, didn't take it to seriously.
Was not too difficult. three total interviews all on the same day back to back. technical one, behavioral one and a case which was more of just a debugging question
